Thread hole correction, thread hole repair, bolt hole repair permanent measures, cast iron crack repair.
MS inserts are ideal for repairing damaged screw holes and bolt holes. They can handle cracked areas around the holes and perform well even in harsh environments.
"MS Insert" is a female threaded part used to repair damaged bolt holes. An insert that applies a special structure to the outer diameter thread is embedded in the bolt hole area for regeneration. It is designed to be difficult to pull out and does not put stress on the base material, making it suitable for areas that are constantly exposed to vibrations or at the ends. Compared to conventional products such as spring-type coils and self-tapping items, it improves precision and demonstrates groundbreaking effects in terms of durability. Additionally, by applying it in areas where bolts are frequently attached and detached, permanent measures can be implemented. 【Features】 ■ Difficult to pull out and does not stress the base material ■ Ideal for permanent solutions for threaded holes ■ Can be used to strengthen and restore thread profiles ■ Enables application at the ends → The upwardly designed thread profile attracts the surrounding base material towards the center of the screw from all directions.

Company information
The mechanical stitch metal crack repair technology is a method that physically repairs metal cracks using special bolts and reinforcement plates (mechanical stitch method), which does not apply heat to the repair area, thus preventing thermal distortion in the crack repair (Mechanical Stitch method). In addition to metal crack repair, it also has the technology to regenerate damaged screw threads using repair inserts. Furthermore, since repairs can be performed on-site, it allows for reduced construction time and cost savings.
